Metabolic liver dysfunction can be a causative factor for morbity and mortality in Berardinelli–Seip syndrome patients. We evaluated hepatic function in 29 Berardinelli–Seip patients. Diabetes mellitus (DM) was present in 23 of them. We analyzed biochemical parameters including AST, ALT, GGT, ALP levels and liver non invasive imaging aspects. The liver was graded as normal, mild, moderate, or severe hepatic steatosis.Results: We could not find ...

Introduction: Insulinomas are pancreatic endocrine tumors originating in the beta cells, characterized by hypoglycemia resulting from insulin hypersecretion.Objectives: To characterize the demography, the clinical features, imagiological findings and pathological evaluation of the cases of insulinomas identified in the previous 35 years at São João Hospital.Methods: We retrospectively analyzed the cases diagnosed as insul...

Introduction: Femoral head avascular necrosis is a dangerous complication that can occur during glucocorticoid therapy, its frequency having been counted up to 40% of patients using corticoids. Even though the complete mechanism involved in this steroid-induced injury is not completely elucidated, studies have shown there’s some relation to bone remodelling, bone vasculature disfunction and apoptosis. We report here a case of femoral osteonecrosis associated to a very low...

Background: Cranial diabetes insipidus (DI) is characterised by the inability to produce vasopressin leading to uncontrolled diuresis. Management includes administering synthetic vasopressin analogue desmopressin (DDAVP). Recently, there have been several national reports of DDAVP omission causing serious patient harm. This study aims to evaluate the feasibility of an automated alert system using Natural Language Processing (NLP) in electronic health records (EHR) to detect DI...

Acromegaly is a rare condition and is frequently associated with infertility. There are very few reported cases of pregnancy in these patients, particularly after surgery and radiosurgery. This is a case of a 29-year-old woman with a 1-year history of nasal obstruction, headache and amenorrhea. She was mother of a 5-year-old child and was trying to get pregnant again, unsuccessfully. Clinical examination revealed coarsening of the facial features, hand and feet enlargement, hy...

Introduction: Hashimoto thyroiditis (HT; with anti-thyroid peroxidase antibodies (TPOAb)) and Graves’ disease (GD; with TSH receptor antibodies (TRAbs)) are frequent autoimmune disorders responsible for thyroid dysfunction. There are two types of TRAbs, the ones that stimulate the thyroid (TSAb) causing Graves’ hyperthyroidism and those that block thyrotropin action (TBAb) being occasionally responsible for hypothyroidism. Unusual patients switch from TSAb to TBAb (o...

Background: Hypoglycemia is a common complication of Diabetes Mellitus treatment, especially in patients receiving intensive therapy. It can cause severe clinical consequences and is an obstacle to achieve glycemic targets.Methods: Retrospective study of severe hypoglycemia due to insulin or oral drug therapy that lead to hospitalization in a central hospital. We reviewed the medical records in the last 7 years (2006–2012) for blood glucose levels a...

Introduction: Fine-needle aspiration cytology (FNAC) of thyroid nodules can be associated with non-diagnostic (ND) results, despite the usage of ultrasound (US) guidance. It is recommended to repeat the FNAC because of the possible risk of malignancy in these nodules.Aim: To evaluate the influence of demographic, clinical and echographic characteristics in the recurrence of ND FNAC in a thyroid nodule.Methods: Retrospective review ...

Introduction and objectives: Poorly differentiated thyroid carcinoma (PDTC) is a rare but aggressive thyroid tumor. PDTC frequently presents in advanced stages and conventional treatments are usually less effective than in differentiated thyroid carcinoma (DTC). Lenvatinib is a multi-kinase inhibitor approved for the treatment of radioiodine-refractory DTC, with significant improvement in progression free survival. Despite the inclusion of a minority PDTC patients in SELECT tr...

Background: Chordomas are rare, invasive and slow growing bone tumours with different locations. Parasellar chordomas are even more rare and the initial manifestations include visual and/or neurological symptoms. In addition, endocrine dysfunction may be present. We describe 4 cases of parasellar chordomas.Clinical cases: 1) Female, 55-years-old, reported headache associated with restriction of left eye movement for the past 3 months. Brain magnetic reso...
